Airport solid state surveillance radar RL-71 S
General Description:
RL-71S is an Airport Surveillance Radar equipped with fully solid state transmitter intended for detection and control of air traffic in the airport terminal area up to distance of 150 km. The radar consists of Antenna Unit, Radar Head Electronics and Dispatcher Room Equipment. Input radar sub-systems are doubled for reasons of radar reliability increase. Detection / target data processing is utilised own AMTI technology capable of optimal adjustment of radar parameters. Display presentation is provided on large-screen LCD monitors completed by VHF/UHF transceivers and Recording / Reply Unit. Radar system can be supplied through two alternative power sources; short supply drop-outs are covered by installed UPS. RL-71S basic version includes also SSR Radar Unit fully implemented into radar system.
RL-71S Radar System uses modular structure enabling possibility to respect customer's wishes. RL-71S radar system parameters comply with all ICAO and EUROCONTROL recommendations.
